Plain-language summary
This study will investigate the mechanisms of cognitive-behavioral response to medications used for relapse prevention in opioid use disorder (opioid addiction, OUD), through investigation of the neural circuits underlying key cognition functions. The study will use previously validated cognitive probes, functional Magnetic Resonance Imaging (fMRI), and novel extended-release injectable preparations of opioid partial agonist buprenorphine and antagonist naltrexone, in OUD patients to explain the individual heterogeneity of OUD treatment response.

✕. Polysubstance users whose drug of choice is not opioids.
✕. Contraindications for XRNTX or XRBUP e.g. active liver disease.
